I can confirm that the changes done in PKGBUILD are working ok on aarch64 (RaspberryPi 400, but for any other board the result should be the same), using makepkg.

There is a problem with the check function:

/usr/bin/xvfb-run: línea 180: 23106 Violación de segmento  (`core' generado) DISPLAY=:$SERVERNUM XAUTHORITY=$AUTHFILE "$@"

that it is solved after installing tk package (does not come by default when installing python on raspberry pi) or configuring a Matplotlib backend.

To avoid dependency on xvfb-run, the check() function can be modified to:

check() {
  cd control-$pkgver
  export MPLBACKEND=agg
  # slycot 0.4 precision errors
  donttest="test_bdschur or test_modal_form or testBalred"
  #xvfb-run --auto-servernum pytest control/tests -k "not ($donttest)"
  pytest control/tests -k "not ($donttest)"
}

For those struggling with installation of this package with current versions of python-numpy (please check also my comment in python-slycot, and if the maintainer has some spare time he can also update this PKGBUILD):

I get the following error during installation:

"Missing dependency python-numpy<1.23.0"

While numpy is currently at 1.25.1

bnavigator commented on 2021-03-24 23:42 (UTC)

Python2 is no longer supported

amael commented on 2021-03-24 20:00 (UTC)

I got an error building the package: pytest was not available

You may want to add python-pytest to the check dependencies, I did that and it worked for me.

m-pilia, the python2-scikit-build package maintainer, recommends the following workaround:

"As a workaround, since this seems to be only an issue with the pytest setup, you can delete or comment out the check() function from the PKGBUILD file" (of the python2-scikit-build package).

It worked and python-control installation was completed.

The PKGBUILD already depends on python-slycot as of this commit: https://aur.archlinux.org/cgit/aur.git/commit/?h=python-control&id=8d96210bb1c8

fernando_morais commented on 2019-10-29 01:29 (UTC)

@calcmogul: python2-scikit-build was updated on 2019-10-03. https://aur.archlinux.org/packages/python2-scikit-build/

calcmogul commented on 2019-09-29 03:54 (UTC)

python-slycot currently doesn't compile because python2-scikit-build doesn't exist (and that's been brought up in a comment on python-scikit-build). I'll update the dependency once that's fixed.

bnavigator commented on 2019-09-28 18:35 (UTC)

I made a PKGBUILD for python-slycot. python-control should depend on that instead of python-slycot-git
